ANTMINER S2 Discussion and Support Thread

[Und3rd0g]

Is there any plans to make these S2's wifi capable?

I might snag one if the price ever becomes reasonable.

I need to be able to toss it in another room with wifi because HEAT&NOISE.

maybe you can use a wireless ethernet bridge/adapter, something like this http://www.netgear.com/home/products/connected-entertainment/gaming-home-theater/WNCE2001.aspx

Excellent call on the Netgear wireless adapter.  Exactly what I needed!  I just bought one on ebay for $22.  Thanks!

Hey guys, is the temp sensor just broken on chain 4 of this S2 or is one of my cards not hashing?



I'm getting 1050 GH/s @ 206mhz.. does that sound about right?

It's just the temp sensor, you have all ten cards hashing according to this screen.  Did you upgrade your power supply?

This most likely happen because one of your cards temperature sensor is not working but mining on it's way and you have no other problem.

What's the deal with people happily snatching up S2's that will never ROI?

If you buy the S2 for 3.769 bitcoins you'll ROI sometime around summer 2015 without factoring in electricity

Who is buying these fucking things?

I'm using mine to build a robot, I assumed that's what we were all doing....

Robot.  Hadn't thought of that.  I'm just using mine to generate heat and noise.

Oh, the robot generates plenty of heat and noise, it just does that while destroying buildings and stealing pretty ladies.

Oh, you're the lucky one, my robot keeps corrupting its cheap memory card, so all I could get it to do is dry the washing

Thanks.. quite a relief.

No, I didn't upgrade. Still running the stock Enermax Revolution87+. Most PSUs will do a little over their specification. It's still the limiting factor on this machine, though. I tried to push it a little further, and while the asics could handle the extra load, the PSU couldn't.

What frequency did you finally decide on? I'm poking on the numbers this weekend and would welcome the input!

Well, yeah.. it's a bit dicey isn't it. At 206mhz the machine's stable. That's where I'm at right now. I get a large number of rejected/stale shares (~2.5%), but that still provides for a better overall hashrate than 196 or 200.

At 212 the machine will run for about an hour, maybe two, then shut down, presumably because the PSU can't handle it. I've tried repeatedly to get it to run continually, but eventually it always goes kaput..

In the end I'll probably just end up upgrading PSUs, because I know the chips can take it. Temps are not an issue regardless of speed - always below 60. I figure that anything below 75 is safe, so there's lots of headspace.

You'll find a list of frequency codes on this thread: https://bitcointalk.org/index.php?topic=589429.0;all

Hope this helps & good luck.

Cheers for this link, I appreciate it.  I'm going to bring in a second PSU over the weekend and split the PCI-cables, we'll see how well it works out!

Can someone post a keystroke by keystroke tutorial or a link on how to putty into an S2?
There was plenty of 'how to' when the S1 came out yet still a dearth of information on S2.

There is no S2 left to buy so don't buy coupons.

[nottm28]

I don't get it - no PSU and no case and only $49 cheaper than an assembled full unit?

How is that AWESOME???

[nottm28]

How much btc do you make every single month if you have 5 units of AntMiner S1

1.43 according to https://bitcoinwisdom.com/bitcoin/difficulty

But don't forget difficulty rises approximately every 12-13 days
